IMPROVEMENT IN HARVESTERS.

Speeication forming part of Letters Patent No. 117,514, dated August 1,1871 antedated July 21, 1871.

To all whom t may concern:

Beit known that I, CHARLES GLAPP, of Trumansburg, in the county ofTompkins and State of New York, have invented a new and usefulImprovement in Harvesters; and I do hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying drawing making part of this speciflcation Figure l being aplan of a harvester provided with my improvement; Fig. 2, a verticalsection thereof in a plane cutting from front to rear.

Like letters designate corresponding parts in both figures.

The object of this invention is to eifect an im` provement especially inthat kind of harvcsters shown in the drawing and described in thespeciiication of Letters Patent of the United States granted to mebearing date the 10th day of May, 1870, and numbered 102,7 7 6, in whichthe cutting apparatus is made to rise and fall by having the inner shoeand grass-shield attached to or connected with a sleeve which turns orvibrates on a tube covering the crank-shaft of the cutterbar, and theinvention is more particularly adapted to that kind of machine; and theinvention consists in a flexible brace or brace-chain so connected withthe pole, with the iiange which supports the ilmer shoe of the cuttingapparatus, and the frame of the machine back of and below the main axle,as to relieve the said iiange and its sleeve from strain in drawing themachine, and to give support to the said flange when the machine is inmotion, substantially as herein specied.

Let A A represent the driving-wheels of the harvester; B, the cuttingapparatus, O, the grass-shield and inner shoe combined D, the

sleeve to which the latter are connected; E, the

flange on the side of the sleeve and forming the connection between thesame and the inner s hoe 5 and l?, the pitman of the harvester. Acasting,

F, forming atubularproj ection of a head or frame in which the axle Grevolves, receives and forms the bearing of the crank-shaft. Forward ofthe axle this tubular projection F has the form of a skein, fittinginside of the sleeve D, .so that the crank-shaft revolves inside of it,and the sleeve D turns or vibrates on the outside of it. The rear end ofthe sleeve D has a flange, a, which iits under and behind a lip, a', onthe tubular projection F, so as to keep the sleeve in place, and, at thesame time, allow the sleeve with its liange E to vibrate freely on thesaid skein of the projection. Heretofore the practiceV has been toattach a chain, O, to a lug on the flange E, as close tothe sleeve D aspossible, and connect the said chain with the pole T of the harvester,

and thereby give support to the said flange and the inner end of thecutting apparatus. But, by thus attaching the brace-chain, a strongdraft or strain comes upon the sleeve D in such a manner as to produce apowerful drawing action on the lip aand flan ge a, thereby frequentlycausing the saidparts to break and always to rapidly wear aw ay. B y mypresent invention the iexible brace or brace-chain O is attached to thetubular projection F back of the line of the main axle and beneath it,the attachment being, by means of a hook, H, or its equivalent, boltedupon or cast with the tubular projection. The brace-chain thence extendsforward through a loop or eye, p, on the iiange E near the sleeve D, asshown, and thence forward and upward to the pole T. The loop p may alsobe either cast upon or attached to the iiange E. Thus the strain on thesleeve D and its iange a, as well as on the hook or lip a', is relieved,and the support is transferred back to the frame portion supported bythe main axle, and no part is liable to give way and none of the workingparts are subjected to undue friction.

What I claim as my invention, and desire to seciue by Letters Patent,is-

The brace-chain O, attached to the frame or tubular projection F and tothe pole T, and supporting the flange E of the sleeve D by means of theloop p, substantially as and for the purpose herein speciied. Y
